WARNING

Electrical Shock Hazard Disconnect power before servicing.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

DIAGNOSTIC GUIDE

Before servicing, check the following:

■Make sure there is power at the wall outlet.

■Has a household fuse blown or circuit breaker tripped? Time delay fuse?

■Is dryer vent properly installed and clear of lint or obstructions?

■All tests/checks should be made with a VOM (volt-ohm-milliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000 ohms per volt DC or greater.

■Check all connections before replacing components. Look for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.

■A potential cause of a control not functioning is corrosion on connections. Observe connections and check for continuity with an ohmmeter.

■Connectors: Look at top of connector. Check for broken or loose wires. Check for wires not pressed into connector far enough to engage metal barbs.

■Resistance checks must be made with dryer unplugged or power disconnected.

SERVICE DIAGNOSTIC MODE ENTRY

These tests allow factory or service personnel to test and verify all inputs to the machine control electronics. You may want to do a quick and overall checkup of the dryer with these tests before going to specific troubleshooting tests.

ACTIVATING THE SERVICE DIAGNOSTIC MODE

1.Be sure the dryer is in standby mode (plugged in with all indicators off, or with only the DONE indicator on).

2.Select any three buttons and follow the steps below, using the same buttons (remember the buttons and the order that the buttons were pressed):

Within 8 seconds,

Press and Release the 1st selected button,

Press and Release the 2nd selected button,

Press and Release the 3rd selected button;

Repeat this 3 button sequence 2 more times.

3.If this test mode has been entered successfully, all indicators on the console are illuminated for 5 seconds. If there are

no saved fault codes, all indicators on the console will momentarily turn off, then only the WET indicator will come on and stay on constantly.

IMPORTANT

Electrostatic Discharge (ESD)

Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the machine control electronics. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

■Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in

the appliance

-OR-

Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

■Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.

■Avoid touching electronic parts or terminal contacts; handle machine control electronics by edges only.

■When repackaging failed machine control electronics in anti-static bag, observe above instructions.

Unsuccessful Activation

If entry into diagnostic mode is unsuccessful, refer to the following indications and actions:

Indication 1: None of the indicators or display turns on.

Action: Select any cycle.

If indicators come on, try to change the function for the three buttons used to activate the diagnostic test mode.

If any button fails to change the function, something is faulty with the button, and it will not be possible to enter the diagnostic mode using that button. Replace the user interface and housing assembly. See Accessing & Removing the Electronic Assemblies, page 11.

If no indicators come on after selecting the cycle, go to TEST #1, page 5.

Indication 2: Console indicators begin flashing immediately.

Action: If console indicators begin flashing on and off immediately, replace the user interface. See Accessing & Removing the Electronic Assemblies, page 11.

Activation With Saved Fault Codes

If there is a saved fault code, only the WET indicator

will be flashing. Review the Fault/Error Codes table, page 2, for the recommended procedure.

Fault/Error Code Display Method

Fault codes are displayed by a series of flashes of the WET indicator. All fault codes have an F# and an E#. The first set of 0.5 second flashes should be counted and used as the F#. The F# indicates the suspect System/Category. The second set of 0.5 second flashes should again be counted and used as the E#. The E# indicates the suspect Component system. The transition from the F# to the E# is indicated by a 2 second pause. After the E# is displayed, there will be a 5 second pause before the F# is flashed again.

Below shows how F3E6 would be displayed:

3 flashes 2 second pause 6 flashes 5 second pause

used to activate Service Diagnostics

Repeat beep tone Second most recent fault code is displayed.

Repeat beep tone Third most recent fault code is displayed.

Repeat beep tone Fourth most recent fault code is displayed.

Repeat Triple beep, then back to the most recent fault code.

Up to four Fault/Error codes may be stored. When the oldest fault code is displayed, additional presses of the 3rd button will result in a triple beep, then a cycling back to the most recent fault code. If each press of the 3rd button results in a triple beep and the WET indicator is constantly lit, no saved fault codes are present.
